    I am currently reviewing a pair of "bookshelf" speakers. I began by placing them in the mid point of my room - - a spot where some other speakers, including the Gemme Audio Vivaces - - work well. However, the new speakers are bass-shy so I had to put them closer to the front wall, so as to get some bass reinforcement. That worked reasonably well but I couldn't shake the feeling that they had more potential than I was hearing. So last night I decided to try them on the long wall (though still close to the wall behind them). Wowsers!!!! The results are even more than I could have hoped for.

    For the next few weeks, I will have to move speakers and connections when I toggle between music and HT, but the results are well worth it.

    Take home message: Room acoustics are complex and highly system-dependent, so don't be afraid to experiment.

    ;)

    I measured years ago - - it's approximately 8" in length, 6" in circumference...Oh wait, you mean the acoustics.... :laugh::laugh::laugh:

    Kidding aside, I don't have the necessary measurement gear but intend to get some in the near future.

    Speaking of room acoustics, what about the new room? Any interest or movement?

    Artie:

    Later this week I should receive from my architect the first preliminary plans, for both the music room and the other home additions. Those for the former will then go to Alan Goodwin (of Goodwin's High End audio).

    I wil keep you posted -- promise.

    Unfortunately, not yet. I've accepted that it is going tot ake a few more months. While I am not thrilled (understatment) by the extra mortgage payments, in a way it is good as the new place won't be ready until the late spring/early summer.

    ah, long wall// short wall set up scenarios.
    Dunlavey/ Harbeth/Snell (AN-e) preferred Long wall.
    X axis at ear or in front....treat the wall behind you extensively.

    first off you know setting either your transducers or your ears
    at the midpoint isn't usually the best location all things
    being equal (& they rarely are in life :crying:) Are you able to
    do a 'cardas' arrangement? Get out the tape measure.

    Larry you really ought to consider ETF-5 or True-RTA
    these are not expensive PC based measurement systems.

    Also Larry you might want to look into buying some simple
    "Plantation shutters" premade, standard size for simple casement
    window openings. 3" shutter depth. Hardwood is nice for sound.
    These will provide you with sound deflection/diffusion.
    You can if you like place some absorbtion behind the shutters.
    These will be affrodable, transportable & beneficial.

    Glad you found a wowsers moment.

    So give us a hint, 2 way speaker...stand mount or floorstander?
    5" 6" 7" 8" midwoofer

    Will this review be online?

    How & where do you have your Devore's set up?

    this past Fall I set up some speakers outside on the back deck.
    invited a couple of hi-fi guys to have a listen....told them that
    removing the room from the eqaution would be enlightening.
    It was & they were slack jawed.

    I will get the measurement gear when I move into the new room. Ditto for shutters. As I will be moving soon, no money will be put into the existing room.

    The speakers are the single driver, Lowther D55-based Teresonic Magus. I am using the integrated stands (not shown).

    The DeVore Super 8s are in my seocnd system but when I had them in the main listening room, thye worked best nearer the front wall. In contrast, the DeVore "The Nines" worked best in the center of the room, as do the Vivaces. I tried a "1/3, 2/3, 3/3" setup but it is not as good as the half-way point.

    Agreed, especially about the ETF-5 software.

    If you are on Mac, FuzzMeasure Pro 3.0 is also excellent.

    The you have to buy a microphone (a Behringer ECM8000 would be a good choice), a mic preamp, and an external USB card to connect to your computer.

    Nice project, Larry. :cool:

    Thanks for the recommendations. As I said, it is my intention to incorporate these when I move.
